\(\left(x-2\right)\cdot\left(y-5\right)=60\)

\(=>x-2;y-5\inƯ\left(60\right)\)và x; y thuộc N

\(Ư\left(60\right)=\left\{1;2;3;4;5;6;10;12;....;60\right\}\)

Sao cô bạn cho 60 zợ, lắm ước quá

Nếu x - 2 = 1; y - 5 = 60 thì x = 3; y = 65

Nếu x - 2 = 2; y - 5 = 30 thì x = 4; y = 35

Nếu x - 2 = 3; y - 5 = 20 thì x = 5; y = 25

Nếu x - 2 = 4; y - 5 = 15 thì x = 6; y = 20

Nếu x - 2 = 5 ; y - 5 = 12 thì x = 7; y = 17

Nếu x - 2 = 6; y - 5 = 10 thì x = 8; y = 15

Nếu x - 2 = 10; y - 5 = 6 thì x = 12; y =11

Tương tự bạn tìm hết đi nhé

b, xy + y = 11

=> y . ( x + 1 ) = 11 ( Áp dụng tính chất phân phối của phép nhân vs phép cộng )

=> \(y;x+1\inƯ\left(11\right)\)và x; y thuộc N

\(Ư\left(11\right)=\left\{1;11\right\}\)

Nếu x + 1 = 1 ; y = 11 thì x = 0

Nếu x + 1 = 11; y = 1 thì x = 10

Vậy ............
